Static Analysis of Circular Cylindrical Shell Under Hydrostatic and Ring Forces

Abstract

Analysis of circular cylindrical shell under the action of hydrostatic and stiffening ring forces is carried out in this work. The differential equation of equilibrium, similar to that of beam on elastic foundation, was obtained from static principles on the assumptions of P. L. Pasternak. The initial value method was used to solve the obtained fourth order differential equation for both cases of hydrostatic and ring forces. Combined actions of hydrostatic and ring forces were studied as the location of the ring was varied along the height of the reservoir. It appears that the most favourable location for the ring is 2/3 of its height measured from the top. Bending moment, shear force and hoop tension diagrams, essentially necessary for design of the reservoir, were plotted under the action of these forces.

Analysis of S-S Short Cylindrical Shells Under Internal Hydrostatic Pressure Using Polynomial Series Shape Function

“…Cylindrical shell tanks are widely used in the construction of strategic water or oil reservoir all over the world Yukun et al [4] In order to lower the cost, and to make the management easier, the volume of such tanks tends to be larger, thus short cylindrical shell. Osadebe and Adamou [5] studied Static Analysis of Cylindrical shell under hydrostatic and Ring forces using initial value method. Ventsel and Krauthammer [6] studied short cylindrical shell using the Krylov's function but did not consider the case of axisymmetrically loaded with internal hydrostatic pressure.…”
